    I decided to start posting everything here as this is a work in progress. I plan on posting all of the past builds in abbreviated form. Today I did my hand casts. I did them years ago in plaster but After seeing Made007 do his in resin I decided to give it a whirl as I think they will be more durable.  So here they.

    The first one turned out to be somewhat experimental. I pulled it out to soon and screwed up the finger tips and I wanted it to be further up my arm. Here weird, that is a blister healing on my finger.

    I built a box to try and use as little alginate as possible.

    I hung a blow drier to keep it as dry as possible while I prepared the resin.

    What kind of resin? Are you accounting for the shrinkage in most poly resins? 1630 positives are the way to go

    Glad to see you made a thread for topknot :)
    Your box idea is great, i see you used alja safe, i used some dental stuff
    My first batch the thing got dried too fast i couldnt make anything with it i lost it , i used room temp water, then i made my second batch with cold water, it gave mo more time to put my hand in place , but it was so cold to hold my hand there, i cant wait to see what hands design you have in mind for topknot :)

    Hey pygreek, now ya tell me. I looked into that (a little late now) and it does look like good stuff, about twice the compression and twice the shear strength. The 320  I used has minimal shrinkage so I think it will be ok. My next batch of resin will be 1630. Thanks . Hey made007 the monster makers alginate worked great. Thanks for the inspiration of your hands. I will probably set these to the side until I get the legs done. Who knows.

    Wish id done mine out of resin, when I did my left hand, I ended up having to break the hand up to get it out of the mould hehe.
     
    Looking great as always. :)

    So I am building this post little by little and I thought I would start at the begining. I actually sculpted the Topknot head around 1998.
    If you look close you can see that I added the topknot area later. Here are the only 2 pictures I could find of this thing when I was doing it.
    Man I look young.

    You see the Fangoria mag. That is the only reference pics I could find at the time. The internet was in its infantsy still.

    So to keep this post going I putting up the bio build. I guess this is probably 7-8 years old now. Yes I am a slow loser.
    The first 3 photos are of the sculpt. I made an alginate impression of the mask and cast it in plaster then sculpted on that.
    bio1001.jpg
    bio3001.jpg
    bio5001.jpg

    Here's a couple I took pretty recently of the clay the way it looks now. I forgot it is sitting on a shelf in
    the garage.
    109.jpg
    107.jpg

    Starting on the tiny but expensive (60 bucks) blade release solinoid.

    Then came the jaw latch mechanism. The only way I can explain doing this is because I thought it would look cool when I was taking it off. The trouble is a person would have to be standing pretty close to see it's function. It activates with a push of the thumb on a plate under the chin. It is spring loaded and has a lock for the thumb plate.

    The lock for the jaw mechanism.

    I guess I painted it next.

    Then came the patina 
    012.jpg
    009.jpg

    I had an idea for the visor that I thought was different. I sandwiched three layers. The out side layer  
    was just clear. I did this to reflect the leads I affixed to the top of the visor.
    012-1.jpg
    013.jpg
    001-1.jpg

    The effect.

    003-1.jpg

    The finished inside.
    098-1.jpg
    you can see the super magnets that help it stay on. When I say they snap it into postion I mean they snap it into postion.
    This one is the wiring that goes to the fixture that the 3 hoses will connect to on the outside. The wiring will be inside the hoses
    and go to buttons on the wrist computer. This is for the laser, visor, and blade solinoid.
    105.jpg

    And finally the finished bio.

    Back to the hands. After reading and viewing the Facebook page about mold making I decided I need to work on these hands. First I have to smooth them down and do a little filling to get them ready to mold then cut apart. I plan on making the thumb and pointer come off together as I will be using these as plugs for the Topknot hands. This is a picture from the Facebook site.

    Here is the first hand sanded and filled and painted.

    Hey Lee, thanks dude. I have to say keeping an eye on what you are doing over there does keep me pushing over here. Don't worry there won't be any sadness anytime soon.

    Did a little more this morning. I decided to pour water in it to see how much silicone I would need. Primitive but effective. 3 3/4 cups. This is good as I hope I will have just enough for both hands.

    I will be doing some fiberglassing on it today. I trimmed those square edges off as I think it will fiberglass easier.

    Well it's around 98 degrees in Austin today so you don't have to ask how the fiberglassing went. Ok I'll tell you. HOT! This sure does seem like a lot of work for half a hand. I might have to try selling some of these to try to put my mind at ease for all the time I'm putting into these. On a positive note it is something very new for me so it is pretty fun figuring it all out. Hey ptgreek I got the 1630 in. Thanks for that tip.

    I was wrong earlier it was 103 degrees. I had a good day. Here is the mold half ready for clay and silicone.
    I learned a few things. 1- on the next hand I won't do clay damns down the fingers, I was trying to save silicone but  it was hell fiberglassing. 2- I put the keys a 
    little to far out so the * will be a little wide. 3- it was well worth watching the Youtube vidoe on working with fiberglass. I have done a ton of glassing over the years but I got some good tips. A- use fiber matte not woven matte. The woven matte is much more difficult to get it to form over things. B- presoak the matte in resin, it softens and is really nice to form. It was a good day.

    I went a head a stayed up to pour this last night. Here are the pics from this morning. I am very happy so far with how the molding process  is working. I have never spent this much time making a mold mostly because I used to hate this part. I wouldn't want to do it for a living but it isn't horrible. Buy the way I was wrong twice about Thursday when I fiberglassed this, it was a record high of 106. No wonder that fiberglass kicked so fast. Ha.

    Your work amazes me Jeff.  Seems if you keep going at this rate, Topknot will be done before you know it.  I'm anxious to see what comes out of this mold.  Keep going buddy!
